Hi!
Sorry that it took me so long to respond;
how big is "very big"? Are we talking about a few GBs?

I remember the mailing list having a discussion on how to exchange
these kind of files; I think Ralph A. Schmidt offered his FTP server,
but I don't know how to contact him (aside from this mailing list and
maybe @dk5ras on twitter).

So: Enjoy your weekend,

Marcus Müller
